88 NOVITATES ZOOLOOICAE XXIV. 1917.

 1 Djebel Zaccar, June 1906, Faroult. 



The Tring Museum series from Mauretania consists of 1,361 specimens. 



The British Museum has the following Mauretanian belemia : 7 Meade- 

 Waldo ; 8 Mogador, Leech coll. ; 10 Tangier, 7 ex Dnue coll., 2 ex Bates, and 

 1 J. J. Walker, all ex Salvin Godman coll. ; 1 Biskra, Maj'. 1 El Kantara, May 

 1882, H. J. Elwes. 



The X after the name of the collector denotes that some or all of the 

 specimens consist of the summer brood glauce. Miss Fountaine records the 

 summer brood glauce from Teniet-el-Haad, May — ^June 1904. 



Euchloe belemia x ausonia algirica ? ? 



These six specuuens and some eight or ten others taken by Dr. Nissen 

 are very remarkable ; thej- are undoubtedly in appearance exactly inter- 

 mediate between belemia and ausonia, and as I consider a specimen taken by 

 myself in April 1912 to agree in pattern with them, I treat them as hybrids ; 

 but if, on examination of its genitalia, this specimen should turn out to be only 

 an aberrant ausonia, it is quite possible that we have here an example of a 

 third brood occurring occasionally among the normally double-brooded belemia. 



6 Guelt-es-Stel, April— November 1912-1913, W. R. and K. J. and Faroult. 



18. Teracolus evagore nouna (Luc). 



Anthocharis nouna Lucas, Expl. Scient. de I'Alg. Zool. III. Lipid, p. 350. pi. i. ff. 2. a, b, etc. (1849) 

 (Oran). 



Hitherto this beautiful little butterfly has been placed as a subspecies of 

 daira, Klug, but it agrees better with that author's evagore, which I think is 

 distmct from daira. 



It has two broods, which differ mostly on the underside, that in spring 

 having a dirty pink colouring of the underside of the hindwing. Monsieur 

 Blachier has separated the spring brood from Bislcra as var. biskrensis. I have 

 only one specimen from the Province of Oran, namely, one taken by myself at 

 Ain Sefra, and this certainly differs from all the other ?? in the Tring Museum 

 by having the orange apex much reduced ; but until an equally large series of 

 both broods from Morocco and Oran can be placed side by side with my 325 

 from East and Central Algeria for comparison, I feel unable to decide this 

 point, and shall record all specimens under no^ina Lucas.
